Emma has 2 times as many cards as Jane. Jane has
35 as many cards as Kimberly. If the three of them have a total of 126 cards, how many cards does Kimberly have?
| Emma |
Jane |
Kimberly |
| 2x3 |
1x3 |
|
| |
3x1 |
5x1 |
| 6 u |
3 u |
5 u |
The number of cards that Jane has is repeated. Make the number of cards that Jane has the same. LCM of 1 and 3 is 3.
Total number of cards that the three of them have
= 6 u + 3 u + 5 u
= 14 u
14 u = 126
1 u = 126 ÷ 14 = 9
Number of cards that Kimberly has
= 5 u
= 5 x 9
= 45
Answer(s): 45
